Is the gift from the wife's parents to their daughter's husband, transferred to his account, for him to dispose of, or is it for the wife?

If the wife's relatives transfer money to the husband's account without specifying the beneficiary, the sender of the transfer is the one who has the right to clarify, and their statement is considered valid in case of a dispute. If it is not possible to refer back to them, then if the wife has a private account, the money sent to the husband is his right, unless there is proof that it belongs to the wife. If the wife does not have an account, the money sent by her relatives belongs to her, as transferring it to the husband's account is a means to deliver it to her, and the husband does not have the right to own it unless the wife's family explicitly states so. If they state that the money is for assistance with living expenses, then it should be spent on the needs of the household, the wife, and the children, and the husband should not claim ownership of it for himself.
